COMBINED X-RAY PROTECTIVE CAMOPYKAND TABLE.

Application led October 24, 1823. Serial No. 670,495. y

To all whom t may conocia:

Be it known that I. lilnnio'rr M, Hier? DRIoKs, a citizen of the United States of America, and a resident of Coli-imbus7 in the county of Franklin and State of @hid have invented a new and useful Improvement in a Combined X-Ray Protective Canopy and Table, of which the following is a specification; n

This invention relates to protective devices for use in X-ray therapy.

It is generally known by those versed in X-ray therapy that the rays used must be of sufficient intensity and duration to kill the disease treated, and that rays which will e kill diseases will also destroy normal tissue and blood cells wherefore it is necessary to confine the rays closely to the diseased por tion of the body to be treated.

Various means have been used to localize the exposure of the X-rays, but the devices employed have been found cumbersome, difticult of adjustment and a fewA have been found dangerous to the patient.

An object of my invention is to provide a combined protective canopy and treatment table wherein X-rays may be confined to a limited portion of the body.

Another object is to provide a deviceof this character wherein a patient undergoing treat-ment is precluded from inadvertent contact with the high tension terminals of the X-ray tube.

Another object is to provide a device of this character which is simple in construction and which is operated without diieulty.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

Fig. 1 is a side elevation of a device of my invention.

Fig. 2 is a plan View of the device.

Fig. 3 is an end elevation of Fig. l.

Fig. 4 is a fragmental cross section of a modified form of my device.

The device comprises a treatment table 5 having suitable legs 6 and carrying on the upper face of the top 7 a plurality of guides S'adjacent the longitudinaledges thereof. The guides 8 are arranged in pairs and may be formed of T-irons as shown or in any suit-J able shape. The cano ies 9 are in the preferred form made semi-cylindrical in shape and are constructed of sheet iron or sheet steel with a sheet lead covering 10 mounted thereon.

breakage of the tube.

rI'he edges ll of the canopies 9 carry shortI axles l2 upon which are revolubly mounted rollers `13 which in this case are shown having grooves la for receiving the guides S. For securing` coinpactuess I prefer to mount the axles 12 on the inner side of the smallest canopy and on the outer side of the largest canopy, the intermediate canopies carrying pairs of brackets l5 on which axles l2 are mounted. It is not desired tolimit the invention tothe specific manner of mounting the canopies as it is within the scope'of this invention to provide sharp edged rollers engaging in V-shaped guides or various other mechanica] equivalents thereof. The modified form suggested in Fig. 4l; consists of securing the guide members 8 upon a suitable open frame cfnnprising sides 1.6 and end pieces 1T the unit thus formed being adapted for use upon an ordinary table 18 or it may be mounted upon suitable standards for holding this unit over an adjustable treatment table. f

In operation all of the canopies 9 may be telescoped at one end of the table whereupon the patient may he placed upon 'the table without difficulty. The sections are then rolled to cover the entire body except a narrow section containing the part to be treated. If a very small location is to be treated, a strip of lead-rubber may be laid across the patients body over the exposed portion thereof and a hole of suitable size cut in the lead rubber. i

From the foregoing it will be noted that I have provided means to limit the X-ray exposure to the desired area and location by a unitaryv device which is handled with great facility. The canopies when positioned over the patient, prevent him from accidentallyY bringing his limbs in contact with the X-ray tube and also afford protection in case of The sections of the canopy may be removed due to the comparative small size and correspondingly light Weight thereof.

What I claim is: f

l. In an X-ray treatment table and protective device, the combination of a table and a plurality of canopies impervious to Rntgei rays adjustably mounted above the tai le. i

Q. As a new article of manufacture an X-ray protective device comprising a telescoping canopy mounted for selective adjust r ment above a table.

As a new article olI manufacture an X-ray protective apparatus comprising an adjustable canopy impervious to Rntgenrays 'for mounting above a table and positionable ttor selectivelv coveringy and exposing the top oi said table.

si, An X-ray treatment table and protective apparatus comprising the combination with a table? of ar plurality of telescoping canopies and ifo-operating means carried b v the canopies and the table Alor slidablv adjustinev the anopies over the table.

An X-rav treatment table and protective apparatus comprising the combination with a table, a pluralityY oi' telescoping canopies`r rollers mounted on the canopies, and guides on the table for receiving the canopy rollers for selectively positioning the canopies above the table.

6. An X-rav treatment table and protective apparatus comprisinzg` the combination of a table, longitudinally extending guides adjacent the sides of the table, canopies, and

rollers carried b v the canopies and engagingA the guides 'for providing longitudinal adjustment of the canopies above the table.

T. As a new article of manufacture an X-ray protective apparatus comprising a series of semi-cylindrical canopies impervons to Rntgen-rays telescopically mounted on longitudinal guides.

8. As a new article of manufacture a telescopicall)Y adjustable X-ray protective canopy `forinounting over a table.

9. In a device of the class described the combination with a plurality of semi-cylin drical telescoping canopies, a sheet-lead coveringkon each of said canopies, rollers mounted on the canopies, and spaced guides 'for receiving the rollers for providing independentvadjustnient of the several canopies longitudinally above a table.

In testimony whereof, I have hereunto subscribed my name this 13th day of October, 192s. f
